The three-axis accelerometer of the tilt sensing element has a χ axis, a Ζ μ Ζ 及 axis and a sensitivity value ^, wherein the three-axis accelerometer is in the horizontal direction of the x-axis and the x-axis. The voltage value outputs the sensed voltage value of Ζ1 when the x-axis direction coincides with the gravity direction G. When the two-axis acceleration gauge is in the unbiased state, the X-axis and the x-axis are on the positive horizontal plane, / When the Ζ axis is in the gravitational direction of the geocentric force, the output voltage value of the yaw is χι, γι and η. When the χ axis and the Υ axis of the two-axis accelerometer deviate from the horizontal plane, the X axis and the γ axis are respectively changed to ^ Represented by the Υ' axis and output the sense voltage values of χ2 and Υ2; when the Ζ axis deviates from the ground 1 force direction G Changed to Ζ, the axis represents, and outputs the «voltage value of Ζ2. The angle θ value can be performed by the tilt sensing element 23 or the calibration and skew compensation operation unit 22 to perform the following steps: The amount of change in the sensed voltage when deviating from the horizontal plane (χι_χ2); and the amount of change in the sensed voltage (γι_γ2) when the γ-axis deviates from the horizontal plane is calculated and the deviation of the axis of gravity from the direction of gravity is calculated. Sense voltage change amount (Ζ1-Ζ2); generate a Αχ value = the sense voltage change amount / Sa when the Χ axis deviates from the horizontal plane; generate an Ay value = the sense voltage change when the γ axis deviates from the horizontal plane The amount /Sa; produces an Az value == the amount of change in the sensed voltage when the z-axis deviates from the direction of gravity of the earth/Sa; M334321 produces a value of angle 0 = arctan [(V(Ax2 + Ay2)) / Az].
